APPARATUS FOR SPINNING YARN.

Application filed October 5, 1926. Serial No. 139,625.

My invention relates to improvements to that class of spinnin commonly known as cap spinning, and lias for its object the production of an apparatus whereby the tension of the yarn may be regulated while it is being wound on the bobbin thus obtaining a softer and smoother thread than usually results from ordinary cap spinning machines.

The invention consists in the combination of a spinning ring and traveler with a spindle cap and means whereby the position of the ring in its relation to the bottom of the cap is adjustable thus enabling the operative to vary the tension on the yarn whenever desirable.

The nature of my invention and the manner in which the same is carried into practical effect will be readily understood on reference to thedrawings hereunto annexed and the following description thereof.

In the accompanying drawings Figure 1 represents a sectional elevation of a suflicient portion of a cap spinning frame t0.

illustrate my invention. Figure 2 is an enlarged view of a cap showing in artial section my improved means for ad usting the relative positions of the ring and bottom of the cap. Figure 3 is a partial :plan of Figure 2, and Figure 4 is a fragmentary section on line H of Figure 3 showing the yarn traveler in operative position on the flanges of the ring. I

In the drawings 10 represents a stationary spindle of usual construction fixedly mounted in a longitudinal rail 11 of the machine and supporting at its top a stationary cap 12. The bobbin or cop tube 13 slidably and rotatably mounted on the spindle is stepped in a bearing 14 fixedto the bobbin rail 15 which has the customary reciprocating .ed. A whirl 16 fixed to the bobbin tube imparts rotary motion thereto in the usual 43 manner. Adjustably mounted on the bot-- tom of the cap 12 is a spring collar 17, the lower part of which serves as a holder for a ring 18 provided with upper and lower annular flanges which cooperates with the traveler 19 in imparting a tension to the yarn 20 as it is being wound on the bobbin. The ring 18 is firmly held on the collar 17 by Tneans of the locking nut 21 in a threaded relation with said collar.

In operation the yarn 20 delivered by the rolls 22 and 23 is drawn through the stationary guide eye 24 and thence through the traveler loop 25 and wound on the bobbin. As shown in Figure 1 the ring is in its lowest position with the yarn subjected to the tension imparted by the drag of the traveler only. By means of the adjusting collar 17 the position of the ring in its relation to the bottom of the cap may be raised so that an additional tension may be-imparted to the yarn by the passa e of the yarn against the bottom edge of the cap as well as through the traveler.

I claim:

In a machine of the character described, in combination, a stationary spindle, a bobbin tube slidably and rotatably mounted on said spindle, a cap supported by said spindle, a collar adjustably mounted on the lower part of said cap, a spinning ring support ed by said collar, a traveler coacting with. said ring, and a nut locking the ring to the collar In testimony whereof, I have signed this
